A study on the retention mechanism of solute of liquid-solid chromatography by stoichiometric displacement model

Abstract

Based on the stoichiometric displacement model of adsorption (SDM-A) the stoichiometric displacement model of retention (SDM-R) in liquidd chromatog. was derived directly. The equation derived by this model is identical to that in reversed-phase chromatog. (RPC) and comparison was mode among equations of various models. SDM-R may be used for both monolayer and multilayer adsorption. The parameter, J, in this model, is a constant for PRC and can be used to distinguish LSC from RPC..
